PORTABLE BOOT CONFIGURATION SOLUTION FOR THIN CLIENT DEVICE

Abstract

Certain aspects direct to systems and methods for performing boot configuration of a thin client device with a portable storage device, such as a universal serial bus (USB) storage device. The system includes a computing device functioning as a thin client device, which has an interface under a protocol, such as the USB interface, allowing the portable storage device to be connected to the computing device via the interface. The portable storage device stores configuration data for configuring the computing device. Before booting, the computing device checks if the configuration data exists in a local storage device. If not, the computing device attempts to access the portable storage device, in order to automatically retrieve the configuration data from the portable storage device. Once the configuration data is obtained, the computing device may proceed with booting, and configure the computing device based on information of the configuration data without manual intervention.

Description

FIELD

The present disclosure relates generally to computing device boot configuration technology, and more particularly to systems and methods for performing boot configuration of a thin client computing device with a portable storage device, such as a universal serial bus (USB) storage device.

BACKGROUND

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.

A thin client device or zero client device is a computer solution whose major role is to connect a physical machine or virtual machine via remote access protocol using the operating system (OS) and other applications programmed in the hardware. A thin client device can be a small device with minimal requirement for hardware such as keyboard, mouse, monitor, universal series bus (USB) port or Ethernet card, and can therefore be particular useful for education, health care, gaming, advertisement, or other uses. Once a remote session is established to a server using a thin client device, all the user activity is processed on the remote server, which can be a physical machine or a virtual machine, and the data is stored back in the remote server. Accordingly, the thin clients devices provide high security by storing data in a centralized location if having been configured appropriately to enhance security.

However, it is time-consuming and takes a lot of efforts for an administrator to configure all of the thin client devices one by one manually based on respective deployment location and need, especially when the thin client devices correspond respectively to different types of configuration developed by different vendors.

Therefore, an unaddressed need exists in the art to address the aforementioned deficiencies and inadequacies.

In certain embodiments, the server device 110 may be a provider of resources or services for the computing devices 120, i.e., the clients of the system 100. For example, the system may be a virtual desktop infrastructure (VDI) system, and the server device 110 may be a VDI server, which provides a plurality of virtual machines (VM) for the thin clients (i.e., the computing devices 120), such that all users are accessing or connecting to the VMs) from the computing devices 120. The server device 110 provides most of the resources of the system 100, which will be shared to all of the VMs accessed by the users from the computing device 120. In certain embodiments, the system 100 may include more than one server device 110, which functions as one or more servers. In certain embodiments, a server may be implemented by one single server device 110, or by multiple server devices 110.

FIG. 2 schematically depicts a computing device and a portable storage device of the system according to certain embodiments of the present disclosure. As shown in FIG. 2, the computing device 120 includes a processor 122, a memory 124, a storage device 126, and a USB interface 128, and the portable storage device 130 is a USB storage device, which is connected to the computing device 120 via the USB interface 128. Further, the computing device 120 may include other hardware components and software components (not shown) to perform its corresponding tasks. For example, the computing device 120 may include, but not limited to, other required memory, interfaces, buses, Input/Output (I/O) modules, network interface cards (NICs) and peripheral devices.

The processor 122 is configured to control operation of the computing device 120. In certain embodiments, the processor 122 may be a central processing unit (CPU). The processor 122 can execute any computer executable code or instructions, such as the firmware 150 or other applications and instructions of the computing device 120. In certain embodiments, the computing device 120 may run on more than one processor, such as two processors, four processors, eight processors, or any suitable number of processors.

The memory 124 can be a volatile memory, such as the random-access memory (RAM), for storing the data and information during the operation of the computing device 120. In certain embodiments, the memory 124 may be a volatile memory array. In certain embodiments, the computing device 120 may run on more than one memory 124.

The storage device 126 is a local non-volatile data storage media for storing the computer executable code or instructions and other necessary data of the computing device 120. In certain embodiments, the computer executable code or instructions of the computing device 120 may be implemented as one or more application programs or modules. Examples of the storage device 126 may include non-volatile memory such as flash memory, memory cards, hard drives, floppy disks, optical drives, or any other types of data storage devices. In certain embodiments, the computing device 120 may have multiple storage devices 126, which may be identical storage devices or different types of storage devices, and the computer executable code or instructions of the computing device 120 may be stored in one or more of the storage devices 126 of the computing device 120. In certain embodiments, one of the storage devices 126 may be a basic input/output system (BIOS) chip, dedicated to storing the booting module 160 of the firmware 150 for performing the booting process of the computing device 120.

The USB interface 128 is a communication interface under the USB protocol. In certain embodiments, the USB interface 128 may include a USB port, and the portable storage device 130 may include a corresponding USB cable or USB connector to be inserted in the USB port to create a USB connection, such that the computing device 120 may access the portable storage device 130 via the USB connection.

As shown in FIG. 2, the computer executable code or instructions being stored in the local storage device 126 of the computing device 120 includes firmware 150. The firmware 150 is a collective management software managing the operation of the computing device 120. In certain embodiments, the firmware 150 may include one or more firmware modules, which may be implemented by the computer executable codes or instructions to collectively form the firmware 150. For example, the firmware 150 may include, among other things, a booting module 160. In certain embodiments, the booting module 160 may be an independent and separate module from the firmware 150. For example, the booting module 160 may be a part of the BIOS, which is stored in a BIOS chip.

The booting module 160 is a module configured to perform booting and configuration for the computing device 120. In certain embodiments, the booting process involves a plurality of startup functions for the computing device 120, including without being not limited to: initiation and power-on self-test, identifying the system devices, locating a bootloader software on the boot device, loading and executing the bootloader software, and giving control to the firmware 150 after the booting process. In certain embodiments, the booting module 160, when executed, may determine in a pre-booting process if the configuration data is available to perform the configuration in the booting process. If the configuration data is available, the booting module 160 may perform booting and configuring the computing device 120 based on the information of the configuration data. If the configuration data is not available, or if the configuration data is available but include invalid information, the booting module 160 may generate an alert signal to notify an end user of the computing device 120 that the booting process may not be properly performed.

As shown in FIG. 2, the computing device 120 does not have the configuration data stored in the local storage device 126. However, the configuration data 170 is available in the portable storage device 130, which is connected to the computing device 120 via the USB interface 128. In certain embodiments, the configuration data 170 being stored in the portable storage device 130 may include one or more configuration files, which may be in an INT file format, or other vendor-specific file formats that allows automatic validation and execution. The configuration files may contain different settings recognized by and applied on any of the computing devices 120. In certain embodiments, the settings may include, without being limited to, network configuration of the computing device 120 being static or manual, network recovery, email address recovery, types of operational modes that may run on the same or different virtual machines on the server device 130 for the computing device 120, a number of monitors to be enabled on the computing device 120, and/or the enabling or disabling of resource redirection on the computing device 120.

In certain embodiments, when the booting module 160 runs in a first booting process of the computing device 120 after a firmware deployment or a factory reset is performed to the computing device 120, the local storage device 126 of the computing device 120 may not have the configuration data required to perform the configuration process properly, as shown in FIG. 2. Thus, in the pre-booting process, the booting module 160 may first determine if the configuration data exists in the local storage device 126. Since the configuration data is not available in the local storage device 126, the booting module 160 then checks the availability of the portable storage device 130, and attempts to access the configuration data 170 from the portable storage device 130. Since the configuration data 170 is available in the portable storage device 130, the booting module 160 then retrieves the configuration data 170 from the portable storage device 130, and validates the information of the configuration data 170. If the information of the configuration data 170 is valid, the booting module 160 may then store a copy of the configuration data 170 in the local storage device 126 for future booting use, and then performs the booting process and configuring the computing device 120 based on the information of the configuration data 170.

It should be particularly noted that, in certain embodiments, if the USB connection between the portable storage device 130 and the computing device 120 is lost before the booting module 120 retrieves the configuration data 170 from the portable storage device 130, the booting module 120 may determine that the portable storage device 130 is not accessible. In this case, the booting module 160 may generate an alert signal to notify an end user of the computing device 120 that the booting process may not be properly performed.

In certain embodiments, once a copy of the configuration data has been stored in the local storage device 126 of the computing device 120, the computing device 120 may be properly booted without the need of the portable storage device 130. FIG. 3 schematically depicts a computing device having the configuration data according to certain embodiments of the present disclosure. As shown in FIG. 3, the computing device 120 has a copy of the configuration data 175 stored in the local storage device 126. Thus, in the pre-booting process, the booting module 160 may first determine if the configuration data exists in the local storage device 126. Since the configuration data is now available in the local storage device 126, the booting module 160 may perform the booting process and configuring the computing device 120 based on the information of the configuration data 175, without the need of accessing the portable storage device 130.

A further aspect of the present disclosure is directed to a method for performing boot configuration of a computing device with a portable storage device without manual intervention. FIG. 4 depicts a flowchart showing a method for configuring the thin client device by using the portable configuring device according to certain embodiments of the present disclosure. In certain embodiments, the method as shown in FIG. 4 may be implemented on a thin client (i.e., a computing device 120) of the system 100 as shown in FIG. 1, such as the computing device 120 as shown in FIG. 2 or 3. It should be particularly noted that the sequence of the procedures as described in the flowchart as shown in FIG. 4 may vary, and is thus not intended to limit the disclosure thereof.

As shown in FIG. 4, at procedure 405, the booting module 160 determines in a pre-booting process whether there is configuration data stored in the computing device 120 (i.e., the local storage device 126). If the configuration data 175 is available in the local storage device 126, as shown in FIG. 3, the booting module 160 may proceed to procedure 470 to start the booting process and perform the configuration of the computing device 120 based on the information of the configuration data 175. On the other hand, if there is no configuration data available in the local storage device 126, the booting module 160 may proceed to procedure 410.

At procedure 410, the booting module 160 determines whether there is a portable storage device 130 in connection with the computing device 120. If the portable storage device 130 is not available, the booting module 160 may proceed to procedure 460 to generate an alert signal to notify an end user of the computing device 120 that the booting process may not be properly performed. On the other hand, if the portable storage device 130 is available, the booting module 160 may proceed to procedure 420.

At procedure 420, the booting module 160 determines whether there is configuration data 170 available in the portable storage device 130. If there is no configuration data available in the portable storage device 130, the booting module 160 may proceed to procedure 460 to generate an alert signal to notify an end user of the computing device 120 that the booting process may not be properly performed. On the other hand, if the configuration data 170 is available in the portable storage device 130, the booting module 160 may proceed to procedure 430.

At procedure 430, the booting module 160 retrieves the configuration data 170 from the portable storage device 130. In certain embodiments, the configuration data 170 being stored in the portable storage device 130 may include one or more configuration files, which may be in an INI file format or other vendor-specific file formats that allow automatic validation and execution. Once the configuration data 170 is retrieved, at procedure 440, the booting module 160 checks if the information of the configuration data 170 is validated. If the information is invalid, the booting module 160 may proceed to procedure 460 to generate an alert signal to notify an end user of the computing device 120 that the booting process may not be properly performed. On the other hand, if the information of the configuration data 170 is successfully validated, the booting module 160 may proceed to procedure 450.

At procedure 450, the booting module 160 stores a copy of the configuration data 170 in the local storage device 126 of the computing device 120 for future usage. Once the copy of the configuration data 175 is stored in the local storage device, the booting module 160 may proceed to procedure 470 to start the booting process and perform the configuration of the computing device 120 based on the information of the configuration data 170.

In a further aspect, the present disclosure is related to a non-transitory computer readable medium storing computer executable code. The code, when executed at one or more processor, may perform the method as described above. In certain embodiments, the non-transitory computer readable medium may include, but not limited to, any physical or virtual storage media. In certain embodiments, the non-transitory computer readable medium may be implemented as the storage device 126 of the computing device 120 as shown in FIGS. 2 and 3.

The foregoing description of the exemplary embodiments of the disclosure has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the disclosure to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.

The embodiments were chosen and described in order to explain the principles of the disclosure and their practical application so as to enable others skilled in the art to utilize the disclosure and various embodiments and with various modifications as are suited to the particular use contemplated.
